- device for automatically extinguishing fire,

to the last named uses.

and more particularly for extinguishmg burning oil, gasolene or otherfluid while simultaneously shutting off the supply of such fluid fromthe point of combustion.

My invention is conspicuously useful in preventing accidentalconflagration on automobiles, in motor boats and in connection with gasand gasolcne en ines in general,

and accordingly I have erein described and illustrated a particularembodiment of the inventive idea which is' especially suited It is to beunderstood, however, that the invention may be employed forextinguishing fires however originating.

The invention is illustrated in a preferred form in the accompanyingdrawings, where- 1n- Figure 1 is a plan view of the device as attachedto the rising manifold bf an ordinary gas engine, ,Fig. 2.is a medianhorizontal section of the same, Fig. 3 is an end elevation of thedevice, Fig; 4 is a sectional viewtaken on the plane 4-4 of Fig. 2, andFig. 5 is a section on the plane of Fig. 2.

My invention, broadly stated, comprises the use in combination of meansfor supporting and separating two substances which, when mingled producean extinguishing gas or fluid; a device for rendering the separatingmeans inoperative, whereby these substances are allowed to mingle; andmeans normally restraining the device last mentioned, but adaptedtQIiberate the same when affected by an'abnormally high temperature. Thefirst named agency may be termed the separating suppprt. The secondnamed device is broadly referred to as;

the mingling means and ,the last named element is called the restrainingdevice.

In the preferred apparatus the separating support comprises two bottles10 and 11, of

glass or other material easily shattered car-' ried ina suitable holder.In the form shown this holder comprises a cylinder 12,

suitably perforated in such a manner as to discharge its contents undersuflicientpressure as hereafter'described.

Inorder to facilitate removal of the broken glass after operation of thedevice I prefer to provide a removable lining of'wire netting 13, withinwhich the vessels 10 and 11 are placed. This netting also serves, to.

prevent the broken glass from closing the perforations in the cylinderand preventing escape of fluid.

The holder 12 is closed 'atits two ends by the caps 14 and 15 which arepreferabl screwed onto the holder, 28 shown. 1 'pre fer to provide alock for the outer cap 14, which consists of a spring-pressed pin 16which moves within the hollow boss 17 and enters a suitable cavity 18with which it registers when the cap 14 is screwed home, A cylindricalpassage 19 constituting a gun barrel, pierces the cap 15., preferably.in'an eccentric position, and this passage com- 4 municates with anexterior enlargement intended to receive the removable breech block 20.As clearly shown in Fig. 5., this block is preferably held" in placerbya tapered pin 21, engaging both the block 20 and the surroundingportions of the cap 15. The breech block 20 is suitably pierced toreceive a firing pin 22, and it may be provided with a handle 23. Theblock 20 also carries two cars 24 between which is pivoted a dog 25} onthe pin 26. The upper end of the dog rests upon the base .of the-firingpin 22 and its-lower end 'exte'nds below the i'mder surface of theholder 12. v

., Within the barrel 19 there is laced a suitable bullet cartridge 27,which is discharged by a blow upon the firing pin. In order to providemeans for delivering the necessary blow, the cap 15 carries a cylinder28, closed at its ends by the screw caps 29 30, the

latter of which :is perforated, as shown. Within the cylinder 28 .thestriker bar 31 is adapted to slide forward under the infiu 1 ence of thespring 32. This bar is guided .by the cap 29 and the piston 33. Thecar-' 'tridge, firing pin, dog and striker bar fdr'm the principalelements of the mingling .perature. Preferably this member is renderedinoperative by being destroyed by the 4 other suitable mixture) acidholder.

temperature in question, either wholly or part y. In claiming thismember as one adapted to be destroyed by abnormally high temperature, Iam to be understood as 1neluding partial destruction. Preferably Iemploy for this pu se a cord 34, by which term I intend to inc ude'awire, for instance, of magnesium or other metal which is rapidly burnedwhen exposed to fire.

I mtg also use thread or string impregnated wi salt r or associated withor formed of nitro-cellulose. Indeed any highl inflammable thread, cordor wire, wil answer. The cord 34 Is fastened at one end to the strikerrod 31 and may then be laid or carried to any suitable position withinthe influence of the device where fire is liable to occur, the. outerend of said cord being made fast. In the form shown the cord ls'ca-rriedthrough openings in' the cars 35, 36 and back to the ear 37. It isobviousthat,

the instant that the cord 34 feels the heatofa flame and is partly orwholly destroyed, the striker rod 31 is liberated, and, under theinfluence of the spring 32, it will deliver a blow upon the do 25 whichcauses the firing pin 22 to disc arge the cartridge 27. At once theholder is filled with a mixture of sodium bicarbonate and sulfuric acid(or whereby there is developed an immense volume of carbonic This gas isexpelled, together with the liquid, through the perforationsin theholder, hnder the influence of its own expansion and the gases liberatedfrom the cartridge. The expansive force of these gases is so great thatan atmos ble of sup rting combustion 18 created for a long Theapparatus. so .far described is suificient to act as a fire extinguisherfor all purposes; but, where intended for use in connection with 3devices using gasolene, I prefer to-associate with the elements so fardescribed other mechanism adapted to act harmoniously with it to cut ofithe supply of gasolene or the like in case of fire.

In the particular device illustrated in the drawings, the holder 12 isfastened to the upright manifold 38, as by the clamp 39."

The ca-rbureter 40 is supplied with gasolene by a pipe 41 leading fromthe opening 42 in the cap 15, and the gasolene is led to the hereincapaistance around the perforated the rod '45 is pivotally attached'thcrcto.

The opposite end of the beam 47 hears upon the end of a pin 48, passingthrough the screw cap 49 and having at its lower end a piston 50.- Apassage 51 leads from the barrel 19 directly under the piston 50. \Vhcnthe cartridge is discharged the ressurc of explosion is transmittedthrough the passage 51 to the piston 50. The pin 48 is forcibly lifted,and acts, through the walking beam 47 to lower the valve rod 45. andshut ofl' the gasolene.

My invention is not limited to the use of a cartridge, and, where othermeansare used for breaking down the separation between the activeliquids, the pressure of the extinguishing giases may be relied upon tobe transmitte through the passage 51 and close the valve as described.

Various changes may be made in my apparatus without departing from thescope of my claims, and I'do not limit myself to the details hereinshown and described.

What I claim is--- I 1.
